The 64-year-old has spent most of his adult life in various prisons following a conviction in 1974 for armed robbery.

Ms Williamson, who attended and auction of her husband-to-be’s artwork before appearing on ITV’s Loose Women, said: ‘He will not be in jail for the rest of his days. I will make sure personally he won’t be in jail for the rest of his days.

‘I won’t give up. When I want something I always get it and I want him out and he’s going to be out, end of.

‘Why would I be with a man who has been in jail for so long? I’m in love with the man. I’m not in love with the fact he’s a prisoner.. Behind every prisoner is a person.

‘He’s done some things he’s not proud of but he can only blame himself, he blames no-one else.’

He added: ‘He knows he’s institutionalised. When and if he comes out it’s going to have to be in a structured environment, he can’t just walk down the road. He’s Charles Bronson, people are going to want to stab him, kill him or do something just to get a reputation.

‘He will have to be put in the middle of nowhere, surrounded by professionals and psychologists.’

Mr Bamby said Bronson had changed his attitude to violence. ‘He knows it’s not the way forward.’
